Abstract
Methods are described for the routine determination of some volatile chlorinated aliphatic hydrocarbons in environmental samples of air and water. The procedures are based on gas chromatography with electron-capture detection. The chlorinated compounds are determined in the ranges 1–100 ng l −1 of air and 0.01–10 μg kg −1 of water. The overall repeatability of both methods is 20 % relative. The procedures are easily adapted to the determination of other volatile halogenated materials.
